Aim To estimate blood loss during oral and maxillofacial surgical procedures and to establish correlation between gravimetric/volumetric estimation of blood loss with changes in pre-operative and post-operative values of haematocrit, haemoglobin, body weight and red blood cell count. Materials and Method Gravimetric and volumetric method of blood loss estimation was used during surgery. Pre-operative and immediate post-operative haematocrit, haemoglobin, red blood cell count and body weight along with intraoperative fluids given and duration of surgery were recorded. This clinically estimated blood loss was compared with actual blood loss which was calculated from the Gross formula. Bivariate analyses were performed using paired t test for comparison of pre-and post-value change and correlation among continuous variable was assessed using Pearson correlation test. Level of statistical significance was set at p value less than 0.05. Results Significant reduction was found between mean pre-operative and mean post-operative haematocrit, haemoglobin, body weight and red blood cell count. Blood loss was found to consistently increase with duration of surgery. The study revealed significant difference between estimated blood loss and actual blood loss. ConclusionThe study concluded that gravimetric/volumetric estimation was a reliable method to determine intraoperative blood loss.

Purpose Dental implants have become a definitive method for the esthetic and functional rehabilitation of both partially and completely edentulous arch. There is a significant role of vitamin D in bone metabolism and there are only few human studies that evaluate the effect of vitamin D deficiency on stability of dental implants. The study thus aims to evaluate the correlation of vitamin D deficiency and implant stability in delayed endosseous implant. Methods The study included 20 subjects of either gender in the age group of 20-50 years, who required implant placement for rehabilitation of partially edentulous condition. Vitamin D status was evaluated for all subjects preoperatively. Implant stability was checked postoperatively at three months and six months using Electronic Technology Resonance Frequency Analysis. ResultsThe study found that for every 1 ng/ml increase in Vitamin D levels, the implant stability Quotient value (ISQ) significantly increased by 0.48 at 3 months and 0.62 units at 6 months, which was statistically significant at P = 0.01 and P = 0.002, respectively. Statistical analysis was done using Student Paired t test, Pearson Correlation test and Simple Linear regression analysis. Conclusion Albeit the smaller sample size, the results of the study showed the positive influence of vitamin D on stability of implant. The study thus emphasizes on the significance of screening the vitamin D status of subjects prior to implant placement.

Study Design: With the patient’s desire to shorten the treatment time and to avoid an edentulous condition, immediate loading of implants has emerged as an alternative approach as compared to delayed loading implants for replacing missing natural teeth. The aim of this study is to evaluate the primary stability in immediate loading of dental implants. Objective: To evaluate primary stability and postoperative complications clinically and radiographically. Method: Total 50 patients were treated with immediate loading dental implants. Withdrawal criteria includes patients not returning for checkup, follow-up, or documentation, and patients not following postoperative instruction. Result: Primary stability increases in immediate loading protocol; mean stability was 57 which was adequate at the time of surgery and during healing period. Conclusion: Our study concludes that under appropriate circumstances, medical condition and maintenance of good oral hygiene provide better primary stability in immediate loading protocol.

Objective- this study was conducted to assess the efcacy of buccal fat pad and collagen in surgical management of oral submucous brosis. Study design- the study was conducted on 20 patients with reduced mouth opening due to oral submucous brosis (khanna and andrade classication grade 3 and 4 a), randomly divided into 2 groups. In one group, buccal fat pad was harvested and in other group, only wet bovine collagen sheet was applied as surgical dressing in the intra-oral wound after brotomy. Patencyof both as dressing material were compared. Conclusion- buccal fat pad as an autogenous graft has advantage of better vascular supply, minimum donor site morbidity, better strength and resilience during healing phase. Xenogenic collagen has better availability, no donor site morbidity, ease of application and better coverage of the surgical wound
